For what it's worth, I use the attached scripts as wrappers for java, jar,
javadoc and javac (the javac one is not extensively tested as I use a
Cygwin-compiled jikes for java compilation).  The only caveat is that
filenames passed as parameters to Java programs and custom doclet options
in javadoc are not converted.  You will need to change the *_EXEC values
close to the beginning of the scripts to conform to your system (I have
IBM JDK 1.3).

Hope this helps.  David, feel free to post them on the web page if needed.
I'd also appreciate any comments or bug reports.  Thanks.
